<a name="GtkRecentFilter.description"></a><h2>Description</h2>
<p>A <a class="link" href="GtkRecentFilter.html" title="GtkRecentFilter"><span class="type">GtkRecentFilter</span></a> can be used to restrict the files being shown
in a <a class="link" href="GtkRecentChooser.html" title="GtkRecentChooser"><span class="type">GtkRecentChooser</span></a>.  Files can be filtered based on their name
(with <a class="link" href="GtkRecentFilter.html#gtk-recent-filter-add-pattern" title="gtk_recent_filter_add_pattern ()"><code class="function">gtk_recent_filter_add_pattern()</code></a>), on their mime type (with
<a class="link" href="GtkFileFilter.html#gtk-file-filter-add-mime-type" title="gtk_file_filter_add_mime_type ()"><code class="function">gtk_file_filter_add_mime_type()</code></a>), on the application that has
registered them (with <a class="link" href="GtkRecentFilter.html#gtk-recent-filter-add-application" title="gtk_recent_filter_add_application ()"><code class="function">gtk_recent_filter_add_application()</code></a>), or by
a custom filter function (with <a class="link" href="GtkRecentFilter.html#gtk-recent-filter-add-custom" title="gtk_recent_filter_add_custom ()"><code class="function">gtk_recent_filter_add_custom()</code></a>).</p>
<p>Filtering by mime type handles aliasing and subclassing of mime
types; e.g. a filter for text/plain also matches a file with mime
type application/rtf, since application/rtf is a subclass of text/plain.
Note that <a class="link" href="GtkRecentFilter.html" title="GtkRecentFilter"><span class="type">GtkRecentFilter</span></a> allows wildcards for the subtype of a
mime type, so you can e.g. filter for image/*.</p>
<p>Normally, filters are used by adding them to a <a class="link" href="GtkRecentChooser.html" title="GtkRecentChooser"><span class="type">GtkRecentChooser</span></a>,
see <a class="link" href="GtkRecentChooser.html#gtk-recent-chooser-add-filter" title="gtk_recent_chooser_add_filter ()"><code class="function">gtk_recent_chooser_add_filter()</code></a>, but it is also possible to
manually use a filter on a file with <a class="link" href="GtkRecentFilter.html#gtk-recent-filter-filter" title="gtk_recent_filter_filter ()"><code class="function">gtk_recent_filter_filter()</code></a>.</p>
<p>Recently used files are supported since GTK+ 2.10.</p>
<div class="refsect3">
<a name="id-1.3.22.7.8.6"></a><h4>GtkRecentFilter as GtkBuildable</h4>
<p>The GtkRecentFilter implementation of the GtkBuildable interface
supports adding rules using the &lt;mime-types&gt;, &lt;patterns&gt; and
&lt;applications&gt; elements and listing the rules within. Specifying
a &lt;mime-type&gt;, &lt;pattern&gt; or &lt;application&gt; has the same effect as
calling <a class="link" href="GtkRecentFilter.html#gtk-recent-filter-add-mime-type" title="gtk_recent_filter_add_mime_type ()"><code class="function">gtk_recent_filter_add_mime_type()</code></a>,
<a class="link" href="GtkRecentFilter.html#gtk-recent-filter-add-pattern" title="gtk_recent_filter_add_pattern ()"><code class="function">gtk_recent_filter_add_pattern()</code></a> or <a class="link" href="GtkRecentFilter.html#gtk-recent-filter-add-application" title="gtk_recent_filter_add_application ()"><code class="function">gtk_recent_filter_add_application()</code></a>.</p>
